Frequently asked questions

Why does my PNG transparency become white in the JPG?

JPG has no transparency support. The tool composites your image over the chosen background (default white). Pick a different background color to match your target use.

What quality setting should I use?

For web — 75–85% is usually invisible to the eye and significantly smaller. For print or archival — 92–95%. Below 70% you may see compression artefacts.

Will I lose detail re-encoding a JPG-derived PNG?

Yes — JPG is lossy. Each re-encode loses a bit more detail. Avoid round-tripping through JPG when possible.

What is PNG to JPG Converter?

A PNG to JPG Converter is a tool that changes PNG images into the JPG format with adjustable quality control to balance file size against visual fidelity. It runs entirely in the browser using client-side processing, so files are never uploaded to a server. JPG output is smaller than PNG, making it well suited for photographs and sharing on the web.

Features

Adjustable JPEG quality

A slider from 10% to 100% (default 92%) sets the canvas.toBlob quality parameter, trading file size against visual fidelity.

Custom background fill for transparency

JPG has no alpha channel, so transparent PNG regions are composited onto a solid background color you pick (default white) before encoding.

Client-side only, nothing uploaded

Decoding, compositing, and re-encoding happen in the browser via the Canvas API — the image file never leaves the device.

25 MB file cap, instant re-encode on change

Accepts PNG files up to 25 MB and automatically re-runs the conversion whenever quality or background color is changed.

Example

Input

logo.png — 1024x1024, 1.8 MB, transparent background, quality slider left at default 92%, background color left at default #ffffff

Output

logo.jpg — 1024x1024, ~210 KB, transparent areas flattened to solid white, EXIF metadata stripped by re-encode

Common use cases

  1. 1

    Shrinking screenshots for web pages

    Convert a PNG screenshot to a smaller JPG at 75-85% quality to reduce page weight when transparency isn't needed.

  2. 2

    Preparing images for platforms that reject PNG or alpha channels

    Flatten a transparent PNG (logo, icon export) onto a solid background and export as JPG for uploaders that require JPEG input.

  3. 3

    Archiving photos exported as PNG

    Re-encode a PNG photo export to JPG at a high quality setting (92-95%) for smaller storage footprint with minimal visible loss.

Summary

This tool converts a PNG image to JPG entirely in the browser: it decodes the file with createImageBitmap, draws it onto a canvas filled with a chosen background color (to replace transparency, which JPG cannot represent), then re-encodes it with canvas.toBlob/convertToBlob at an adjustable quality (0.10-1.00, default 0.92). No file is uploaded — the whole pipeline runs client-side and the re-encode strips EXIF metadata and is lossy.
